At the outset, the battle was over White's isolated QP. Maroczy won the Pawn with a little combination on moves 21 to 23, but Tinsley should have equalized by simply taking Maroczy's QBP (24. Bxc6). After that, Maroczy made a series of errors that should have allowed Tinsley to win the Pawn back with 26. Rc3; 27. Rd1; 29. Rc3; and finally with 31. Rc3. After missing all these opportunities, Tinsley was indeed a full Pawn down, and Maroczy never let him back in the game after Move 34.

For reasons I cannot fathom, Tinsley--having decided to play on in his totally lost position-- allowed Maroczy to get a protected passed pawn by his inexplicable 36. b4. But Maroczy--though retaining his winning edge--repeatedly avoided easy/fast ways to put Tinsley out of his misery. For example, why didn't Maroczy snatch Tinsley's hanging h4 with 39...Bxh3 (instead of his feeble 39...Kf2)?

It gets worse. Tinsley's suicidal 46. h4 should have been demolished by Maroczy with 46...Rd2 (instead of his lame 46...Qxb4). After Tinsley's defeatist 48. Rd1 and 50. Kf1, one would have expected Maroczy to have ended the suffering with 50...Ng3 check. Instead, he kept the game going with 50...Nc3. On the next move, Maroczy--being up two passed pawns--decided to trade off Rooks and Knights rather than crush Tinsley with 51...Qf3.

Perhaps wanting to punish Tinsley for playing on in a hopeless endgame, Maroczy declined the chance to push his QBP on move 55 and then then declined the chance to push his QNP on move 56, and extended the "battle."

Maroczy finally won Tinsley's Bishop on move 61, and then after a spite check on move 62, Tinsley at long last gave up the entirely hopeless struggle.
