1) TACTICAL TARGET CAN BE A TACTICAL MOTIF

2) TAKE THE BASE OF THE PAWN CHAIN, REMOVE THE GUARD

3) PIECES OF *OPPOSITE* COLOR LINED UP (White d3-bishop, Black c3-queen) ARE A PREREQUISITE FOR A DISCOVERED ATTACK

19 ♘e5xf7!! 1-0 <UPGRADES> the singular <THREAT> of ♕g4-g3 into a <TACTICAL TARGET (DOUBLE ATTACK)>.

That is why you want to <VISUALIZE> the occupation of the <TACTICAL BASE>, to determine what the <CANDIDATE SQUARES> are for creating a *second* <TACTICAL TARGET> for a <DOUBLE ATTACK>!!!

Game Collection: ENEMY KING makes a great second target

This is the position after Black has just played 18 ... ♕c5xc3?!, capturing a White pawn on c3 *but* also dangerously <LINING UP> his <UNDEFENDED> Black c3-queen with the White d3-bishop, creating the prerequisite White-piece-lined-up-with-Black-piece for a possible <DISCOVERED ATTACK>.

White realizes that he can create said <DISCOVERED ATTACK> by moving his White h4-queen onto the g3-square with 19 ♕h4-g3?, but this move does not really threaten anything and just drops the White g5-knight.

What is the problem? The problem is that when the White h4-queen arrives on g3, it does *not* create a <SECOND THREAT>. The threat of ♕h4-g3 needs to be *augmented*, that is, White needs the arrival of the White h4-queen onto g3 to threaten something besides the creation of the <DISCOVERY CHAIN> White g3-queen + White d3-bishop + <UNDEFENDED> Black c3-queen.

Here is the key: <VISUALIZE> the White h4-queen on g3. What other squares might make a good <SECOND TARGET>. The g6-square stands out, as it is a square that can be reach by the White queen from g3 *and* is near the enemy Black e8-king.

Now what <FORCING MOVE> does White have at his disposal that could make the g6-square a <SECOND TACTICAL TARGET>? 19 ♘g5xf7!!

19 ♘g5xf7!! 1-0

The point is that the brilliant 19 ♘g5xf7!! has created a <SECOND WEAKNESS>, the Black king in general and the g6-square in particular.

After 19 ... ♔e8x♘f7, White *now* plays his h4-queen onto the g3-square with 20 ♕h4-g3 and *now* this queen move is a <DOUBLE THREAT>.

(CONTINUATION)
19 ... ♔e8x♘f7 20 ♕h4-g3

White now has *two*, count'em *two* threats:

GM Baburin in Chess Today CT-3420 gives the sequence <19 ♘g5xf7! ♔e8x♘f7 20 ♕h4-g3! g6-g5 21 ♗d3-g6+ ♔f7xg6 22 ♕g3x♕c3> with great loss of material for Black, so he resigned.

A simply brilliant idea by White, 19 ♘g5xf7!! followed by 20 ♕h4-g3, or 19 ♘g5xf7!, 20 ♕h4xg3! if you prefer Baburin's annotation.

White <VISUALIZED> the White h4-queen on the g3-square <TACTICAL BASE>, where one <TACTICAL TARGET> for a <FORK> was the <DISCOVERY CHAIN> ♕c3-♗d3-♕g3 and the second <TACTICAL TARGET> was the g6-square near the Black e8-king that was created by 19 ♘g5xf7!! and could be reached by the White h4-queen when she arrived on the g3-square.

I'll stop spamming when you become a GM, k.
