Вообщем описание проблемы:

1. При проверке дебаггером вижу что проверка комбинаций происходит
не в тех картах которые уже поменяны, а в картах первого расклада;
2. проверка комбинаций не всегда определяет правильные комбинации.

Народ плиз! помогите найти причину почему запускаемая проверка, просматривает карты которые были выложены первыми а не те которые уже были заменены
