KEG: An undistinguished game that Showalter had several chances to win.Cohn had much the best of the early play, but his 8. 0-0 (instead of the indicated 8. a4) allowed Showalter to get in 8...b5. And after Cohn's weak 9. Qc2 and 10. a3, any opening edge he had enjoyed was gone.
After Cohn's weak 14. Bg3 and 15. Qe2 (he should surely have tried 15. e5), Showalter probably had a strategically won game.
But Showalter's 17...Qb6 (instead of 17...Qe5) forfeited much of his advantage, and his 19...Qc4 allowed Cohn to solve most of his problems by trading Queens.
Showalter did get the better endgame,especially after Cohn's weak 23. Kf1 (23. Bd3 was best), but Showalter's 23...Ke7 missed 23...b4 which would have given him good winning chances. After Cohn's poor 24. Ke2, Showalter erred again with 24...Rd4. Now Cohn could have obtained a playable ending with 25. Bd3. Instead, his 25. Rd1 allowed Showalter to trade off Rooks and reach a highly favorable ending with two Bishops against Cohn's Bishop and Knight.
But Showalter repeatedly spoiled his better position. His 27....a5 and 28...Bc6 allowed Cohn to get in 29. b4.
After 29. b4, Showalter's winning chances had just about evaporated. and after his 31...g5 (31...Be5 was the only way to maintain an edge) Showalter's winning prospects were nil.
