Subject: tiger's play too risky ?

Author: Ulrich Tuerke

Date: 08:49:27 04/06/01


Since nobody is posting wins of my program, I mayself have to do it. -:)

Having got curious on Gambit Tiger, I have made 2 consecutive games on FICS,
comet even running on a bit inferior hardware (700 MHZ - 1 GHz, time control is
4+6.)
The games below demonstrate the high risk of gambit tiger's playing style. I can
hardly imagine a top engine giving this good chances to a middle class freeware
program.

The games ended 1.5 - 0.5 for comet, where tiger rather luckily escaped into a
drawn ending in 2nd game.

These 2 games do of course not imply that comet is stronger. I'm sure, that the
ship will sink in a multi-game match. However, they do demonstrate that far
weaker opponents have a unexpectedly good chance against due to tiger's risky
playing style.

I personally doubt that the gambit version of the program can do better than the
usual tiger against computer opponents.

Regards, Uli
