Summary
Conditions

Analyze Selected Deals

One DSL expression per line (lines starting with # are ignored). Numeric → count/min/max/mean/std. True-or-false → probability with a 95% confidence interval. Text → frequency table. Probabilities are conditional on the filter/constraints that produced these hands. An optional true/false filter restricts the analysed subset; with no expressions and a filter, the run reports the filter pass-rate.

Import Deals

Paste or upload deals in BBO LIN, handviewer URL, or PBN format. A single file or paste can mix all three. Imported deals appear as a collapsed batch in the log.
