Play the first 15 or so moves out rapidly and then see what happens. Black manages to wedge his B deep into enemy territory. He has managed to gain some sort of time/space advatage from this, where white has gained some space on the k side. Can white turn this space into anything important? Maybe not.

Eventually blacks B will manage to pull pawns forward in order to queen, then he sacks the R turning the space advantage into more tempo.

The moves that lead to the end game are pretty nice too. A good practical example of a blockader piece in use. So look at moves 21 through 30 or so. That is where white is finally finished off.

This opening variation was apparently something like 15 to 20 moves deep depending on which line you had memorized. Zaitsev had authored an article on it, based on a game w/ Priydovsky, where Pri. was black and played 15...f5

in the line played in this game (15...Bd4+), Zaitsev was suggesting the continuation with 21...f5 but of course Szabo didnt read the article and he came up with 21...Nb6. it was probably off the top of his head, just sitting there staring at the chess board and probably a better move than the one Z. had come up with.

Anyhow this move 21...Nb6 appears to work because black can answer Bxd6 w/ Nxd5, because the e pawn is pinned to the R; the R is loose and not protected.

WHich brings up the whole question of what is the R doing on e3 in the first place but that that will have to wait for now.

Anyhow I guess Pomar just didnt really worry about the pin and played 22 Bxd6. However, he could have broken the pin essentially by playing 22 R(3)e1

at least I think so. Play the position for awhile and you may see the play sort of revolve pts. e..g d6 and d3. Perhaps white can get an advantage by simply pushing the e pawn through. My theory of chess would tell me that there is some relationship here between time/space here as first one side has the move, they gain some space; then they turn it over.

What if black tries to break up the King side pawns? Does it lead to anything?

Now on 23 R(3)e1 Evans says "The only interesting course is 23 RxB PxR 24 P-B5 (24 PxN? RK7+)" Hmmm now HE wants to sack! Is everyone just sack happy?

On 24...Rxe5:

"Hey Sneaky look at that! a Rook for 5 pawns by drunk count. Looks like Szabo subscribes to the same theory as me."

On 26 Ra3 it looks like something stronger was called for like either: clear the e file of pawns or trade down the N for the passed pawn.

On 28 Nb3 Evans doesnt like it suggests trading down R for B ( 28 RxN BxR) and taking his chances on the end game.

SCID classifies it as E77 (KID-Four Pawns Attack) until 9.cxd5, then switches to A68c (Benoni-Four Pawns), calling it main line until 11.a4
